BWI said it worked with the airport’s concessions developer AIRMALL to provide the free Wi-Fi option for travelers.

"We know travelers today leave the house with a host of wireless devices—from laptops and tablets to wireless phones," said Brett Kelly, vice president of AIRMALL Maryland. "People want to stay connected when they’re on the road, and this complimentary wireless service makes that even more possible."

In February, PCWorld magazine reported that BWI Marshall was among the best U.S. airports for tech travelers. The magazine ranked BWI Marshall among the Top 10 "techiest" airports in the U.S.
